Abstract
The utility model discloses a double-blade wind power generating windmill adapting to gentle breeze. The wind power generating windmill comprises a windmill shaft sleeve and windmill blades, wherein the windmill shaft sleeve is connected with the windmill blades; each windmill blade comprises cross beams, protective plates, separating sleeves, shafts, rotating shafts and four-blade windmills; each windmill blade is connected with the cross beams via the rotating shaft; the shafts are connected between the cross beams; the four-blade windmills are connected to the shafts; each separating sleeve is arranged between each two four-blade windmills; the rotating shaft can adjust an angle between each windmill blade and the windmill shaft sleeve; and each four-blade windmill drives the windmill to rotate by the gentle breeze. Quite gentle breeze can drive the wind power generating windmill; when strong wind comes, windward side intensity of the windmill is strengthened, so generation efficiency is improved; and the double wind power generating windmill has simple structure, thereby being easy to manufacture.
Description
Technical field
The utility model relates to technical field of wind power generation, particularly relates to the double leaf wind power generation windmill that a kind of gentle breeze adapts to.
Background technique
Existing tens thousand of wind energy conversion systems are in operation in the world, as supplementary energy, bringing into play this huge effect, but wind energy conversion system still existing some deficiencys, is first that energy output is unstable, particularly the utilization ratio of large scale wind power machine is low, as the condition of separate energy source, does not also possess; Secondly, the safety reliability of wind energy conversion system there is no abundant guarantee; In addition, the cost of wind energy conversion system is still not enough to compete mutually with mineral fuel in a short time.
In order to solve energy output unstable problem, the oscillating wind windmill that the utility model provides a kind of gentle breeze to adapt to.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the double leaf wind power generation windmill that the utility model provides a kind of gentle breeze to adapt to.
The technological scheme that the utility model adopts is: the double leaf wind power generation windmill that a kind of gentle breeze adapts to, described wind power generation windmill includes windmill axle sleeve, air vane, windmill axle sleeve connects air vane, air vane includes crossbeam, backplate, partition cover, axle, rotating shaft, four leaf wind sheets, air vane connects described crossbeam by rotating shaft, between crossbeam, be connected with axle, on axle, be connected with four leaf wind sheets, between every two four leaf wind sheets, be provided with and cut off cover, rotating shaft is rotated and is adjusted air vane and windmill axle sleeve angle, and four leaf wind sheets rotating drive air vane under a gentle wind springing up rotates.
Compared with prior art, the beneficial effects of the utility model are:
1. very faint wind just can drive this wind power generation windmill;
2. while blowing hard, increased the windward side intensity of windmill, generating efficiency is higher;
3. simple in structure, be easy to realize.
Accompanying drawing explanation
Fig. 1 is that a kind of axle that waits of double leaf wind power generation windmill of gentle breeze adaptation is surveyed view;
Fig. 2 is a kind of plan view of double leaf wind power generation windmill of gentle breeze adaptation;
Fig. 3 is the partial enlarged drawing that a kind of four leaf wind sheets of double leaf wind power generation windmill of gentle breeze adaptation are connected with partition axle sleeve;
Fig. 4 is the B-B sectional view of the plan view of the double leaf wind power generation windmill that adapts to of a kind of gentle breeze;
Fig. 5 is that the C-C of the plan view of the double leaf wind power generation windmill that adapts to of a kind of gentle breeze analyses and observe.
Embodiment
In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be further illustrated, this embodiment, only for explaining the utility model, does not form and limits protection domain of the present utility model.
As Figure 1-5, the utility model is the double leaf wind power generation windmill that a kind of gentle breeze adapts to, described wind power generation windmill includes windmill axle sleeve 9, air vane 8, described windmill axle sleeve 9 connects air vane 8, described air vane 12 includes crossbeam 1, backplate 2, cut off cover 3, axle 4, rotating shaft 6, four leaf wind sheets 7, described air vane 8 connects described crossbeam 1 by rotating shaft 6, between described crossbeam 1, be connected with axle 4, on described axle 4, be connected with four leaf wind sheets 7, between every two described four leaf wind sheets 7, be provided with and cut off cover 3, described rotating shaft 6 is rotated and is adjusted air vane 8 and windmill axle sleeve 9 angles, described four leaf wind sheets 7 rotating drive air vane 8 under a gentle wind springing up rotates.
Preferably, for avoiding described wind power generation windmill in production and processing and safeguarding that operational phase do not destroy four leaf wind sheets, the blade end 7-1 length of described four leaf wind sheets 7 is not higher than the height of the bottom surface 1-1 of crossbeam 1.
Preferably, for increasing the swinging strength of four leaf wind sheets, between described four leaf wind sheets 7 and partition cover 3, leave gap 10, described gap 10 is not less than 0.5mm.
Preferably, backplate 2 is used high-strength bolt 5 to be connected on crossbeam 1 to guarantee its intensity.
Preferably, air vane 8 materials are the working strength that carbon fiber-reinforced resin has not only guaranteed windmill, and have alleviated the weight of windmill, have reduced the frontal resistance of windmill, are to obtain one of key factor for windmill obtains wind-force.
Further, the utility model has adopted 5 four leaf wind sheets that shape is relatively little to pass the same axis, and three same parallel axes are connected to the structural type on air vane framework, two air vanes 8 that are connected on windmill axle sleeve 9 are asymmetric about windmill axle sleeve 9, the deficiency of windmill generating when this structure has made up little wind or gentle breeze also can produce larger electric weight when little wind or gentle breeze.
The double leaf wind power generation windmill that a kind of gentle breeze described in the utility model adapts to, when little wind or gentle breeze, first utilize the weight effect of two asymmetric air vanes to swing, with this simultaneously, four leaf wind sheets 7 on air vane are because weight is lighter, under gentle breeze, swing easily the swinging strength that has increased air vane 8, thereby produce larger electric weight.
Compare with existing wind power generation windmill, the oscillating wind windmill structure that the gentle breeze that the utility model proposes adapts to is simple, be easy to realize, and very faint wind just can drive this wind power generation windmill; When blowing hard, increased the windward side intensity of windmill, generating efficiency is higher.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
